is syntax error?

edit: when click on link, error: uncaught typeerror: document.results.getelementbyid not function

first of all, try using developer's console browser (likely shown "ctrl+shift+i").

for question: javascript case sensitive, "getelementbyid()" won't work; use "getelementbyid()" instead. also, won't work when calling document.[form].getelementbyid(), should call directly: document.getelementbyid(id). nevertheless, have no id's set in html, clicks return 'null' parameter in function.

i recommend try simpler examples first, particular one!
